Tarver and Mason were both Stanford assistants in 2011. Tarver also has been a defensive assistant for the San Francisco 49ers and Oakland Raiders.

Mennenga has been a special teams assistant coach with the Cleveland Browns the last seven seasons. Moorehead, who previously worked with Mason at Stanford, spent the last three seasons as Texas A&M's receivers coach.

Brown was a defensive graduate assistant for Washington the last three seasons.

Vanderbilt went 5-7 last season.
